Abstract
The single crystals of tristhiourea lanthanum nitrate (TTLaN) have been grown by solution growth using slow evaporation technique. The optical study revealed that the crystal has high transmission with lower cut-off wavelength of 235.78 nm. The EDAX analysis confirmed the grown compound elements. The presence of functional groups was identified through Fourier transform-infrared technique. The thermal stability of the crystal was determined from thermo gravimetric and differential thermal analysis curve. The second harmonic generation behavior of TTLaN crystal was tested by Kurtz-Perry powder technique. This single novel semiorganic crystal of TTLaN showed very good optical transmission property, high thermal stability and large non-linearity nature.

A great recital optic switching aspect for optical information and telecommunication dispensation is based on non-linear optical (NLO) materials
An attempt has been made to grow and characterize single novel crystals of tristhiourea lanthanum nitrate (TTLaN) where the lanthanum belongs to rare earth group
The NLO property of TTLaN crystal was tested by Kurtz powder SHG (Second Harmonic Generation) test using Nd:YAG laser (1064 nm)
Summary
A great recital optic switching aspect for optical information and telecommunication dispensation is based on non-linear optical (NLO) materials. Thiourea is used in many industrial applications and as a chemical intermediate, in metal processing, plating and in photo processing. It has a wide range of uses, such as producing and modifying textile, dyeing auxiliaries, and synthetic resins in image reproduction in the production of pharmaceuticals and industrial cleaning agents for etching process in electroplating and as an antioxidant. It is a centrosymmetric molecule; if coordinated with metal ions, it becomes noncentrosymmetric materials showing nonlinear activity. An attempt has been made to grow and characterize single novel crystals of tristhiourea lanthanum nitrate (TTLaN) where the lanthanum belongs to rare earth group
